An apparatus for forming a snap ring groove in a clutch drum by pressing a lower die, an upper die, a workpiece supporting member, first sliding members and second sliding members, a workpiece receiving member fixed on a radially inner end of each first sliding member, and a punch fixed on an upper end of each upwardly bent portion in a radially inner end portion of each second sliding member. The first sliding members and the second sliding members are pushed radially inwards and outwards, respectively, via a cam mechanism by lowering the upper die. The cam mechanism is made of a first cam mechanism for driving the first sliding members and a second cam mechanism for driving the second sliding members. The first cam mechanism is arranged to push the first sliding members radially inwards, when lowering the upper die, with a radially outer end portion thereof operating as a point of action. The second cam mechanism is arranged to push the second sliding members radially outwards, when lowering the upper die, with a radially inward end portion operating as a point of action.

Apparatus for forming snap ring groove in clutch drum

A clutch drum made of a metallic plate having on its peripheral wall portion spline teeth for engaging with clutch plates is formed by pressing with a die which has formed tooth grooves on its periphery and tooth-shaped punches which are disposed around the die so as to move radially back and forth. The force of pressurizing the toothed punches against the tooth flank portions of the spline teeth is made smaller at an open end thereof than at an ordinary portion of the clutch drum such that the thickness of the flank portions of the spline teeth becomes thicker at the open end than at the ordinary portion.

Disclosed is a high-frequency heating apparatus including an elongated chamber in which a plurality of rocker arms are introduced, each of the rocker arms being attached with a chip and brazing filler such as a copper wax, a high-frequency brazing coil for high-frequency heating a designated part of each rocker arm in the chamber to braze the chip to the rocker arm, a high-frequency temperature-holding coil for holding the temperature of the rocker arm constant, and a nitrogen gas supplying device for keeping the chamber filled with a nitrogenous atmosphere during the high-frequency heating.

High frequency induction heating method for rocker arms

A double planetary carrier is constructed by providing separate carriers for carrying therein two sets of planet gears which are axially set apart from each other, and by connecting the two carriers together. A cylindrical portion is formed on a periphery of a side plate of one of the carriers to receive therein a side plate of the other carrier. Serrated teeth are formed respectively on a periphery of the side plate and on the cylindrical portion to connect the two carriers by means of serrations. The serrated teeth are formed so as to have a play therebetween. Between the side plates there are formed radially extending oil grooves to introduce lubricating oil into oil holes which are formed in gear shafts of the planet gears.

A clutch drum has a drum main body made of a metallic plate which is formed into a cup shape by drawing. Spline teeth for engaging with clutch plates are formed by pressing on a periphery of the drum main body. Pulsing teeth for detecting a rotational speed are formed by pressing on the periphery of the drum main body. An apparatus for manufacturing the clutch drum has a forming die onto which the drum main body is externally set in position. The forming die has formed thereon first tooth spaces corresponding to the spline teeth and second tooth spaces corresponding to the pulsing teeth. First tooth-shaped punches are provided so as to be movable radially back forth to form by pressing the spline teeth by urging the periphery of the drum main body into the first tooth spaces. Second tooth-shaped punches are provided so as to be movable also radially back and forth integrally with the first tooth-shaped punches to form by pressing the pulsing teeth by urging the periphery of the drum main body into the second tooth spaces.

High-frequency induction heating apparatus for rocker arms

A disc cutting apparatus for cutting opposite surfaces of a disc-shaped workpiece such as a disc rotor for an automobile disc brake includes a rotating mechanism for positioning and rotating the workpiece which is pressed, under uniform pressure, radially inwardly by a plurality of holder mechanisms. While the workpiece is being rotated by the rotating mechanism and pressed by the pressing mechanism, the workpiece is cut by a cutting mechanism. The cutting mechanism includes cutters for cutting opposite surfaces of the workpiece, and the cutters are positionally adjusted with respect to the workpiece based on positional information detected by a detector which has a probe held against the workpiece.

Disc cutting apparatus

An apparatus for assembling workpieces in which an assembling work is performed includes a workpiece setting jig, a setting station including a workpiece setting apparatus for setting a first workpiece on the workpiece setting jig, an assembling station including an assembling unit for assembling a second workpiece with the first workpiece on the workpiece setting jig, a welding station including a welding unit for welding the first and the second workpieces together, a discharging station including a discharging unit for taking the welded workpieces out of the workpiece setting jig, a charging station provided in a position which faces the setting station as seen in the direction of sending and withdrawing the workpiece setting jig. The charging station, the assembling station, the welding station and the discharging station being arranged in a circular form. A mechanism is provided for circulating the workpiece setting jig among the charging station, the assembling station, the welding station and the discharging station in sequence. A mechanism is provided for reciprocating the workpiece setting jig between the setting station and the charging station. The method of assembling workpieces includes disposing the charging station in a position facing the setting station, and disposing the charging station, the assembling station, the welding station, and the discharging station in a circular form to a side of the setting station.
